JOHN E. WALLING AND ANDY OLSON, OF PORTLAND, OREGON.

HYDROCARBON-BURNER.

To all 'whom it may concern:

Be it known that we, JOHN E. IVALLING and ANDY OLSON, citizens of the United States, residing at Portland, in the county of Multnomah, State of Oregon, have invented Acertain new and useful Improvements in IIydrocarbon-Burnersg and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to malte and use the same.

This invention relates to improvements in hydro-carbon burners and more particularly to the type adapted to burn an admixture of oil vapor and steam.

It has for its object the provision of an extremely simple, inexpensive, and efficient device especially designed for heavy firing.

Another object is the provision of an improved form of burner head so con structed that its outer end will limit the expansion of the steam and oil vapo-r in one direction whereby a perfect admixture of the steam and oil will be effected.

lith these and other objects in view, as will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that various changes, in the form, proportion, size, and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of the specification Figure 1 is a longitudinal sectional view of the improved burner. Fig. 2 is a transverse sectional view thereof, the latter section being taken on the line 2 2 of Fig. 1.

Similar numerals of reference are ems ployed to designate corresponding parts throughout.

The steam supply pipe is designated by the numeral 5 and the oil supply pipe which is of less diameter than the steam pipe and arranged concentric with the latter is designated by the numeral 6.

The inlet casing fitted upon the inner end of the steam pipe is designated by the numeral 7 and adjacent one end is contracted to receive the inner end of the oil Specification of Letters Patent.

supply pipe 6, whereby a casing is formed for the latter designated by the numeral 8.

The needle valve for controlling the flow of oil to the burner head to be presently described is designated by the numeral 10.

The burner head in the present instance is designated by the numeral 9 and is formed of a solid elongated casting, and what will subsequently be termed the inner end portion of this head is circular in cross section and the opposite or outer end rectangular in cross section as shown in Fig. 2. The inner end portion is exteriorly threaded and extending laterally from the intermediate portion of the head 9 is an annular flange 12. The latter being peripherally arovided with an interiorly screw threadec lip 15, extending in a plane with the terminal of the inner end portion 13 of the head.

Formed in the head 9 are three passages 11, which have their inner ends opening into an axial seat 20, formed in the end of the inner end portion 13 of the head, and their outer end-s opening through the outer face of the outer end portion 14- at the point where the latter meets the outer face of the flange 12. These passages are inclined downwardly and have an appreciable divergence from their upper to their lower ends. The How of oil through these pas-- sages is regulated by the needle valve 10, the pointed or inner end of which fits in the seat 20, the outer end of said stem projecting through a bushing 18 located on the rear end of the casing 8. The projecting end of the stem of the needle valve is provided with a small hand wheel 21, by means of which it may be turned in either direction there being a stuffing box 22 threaded upon the bushing 18 through which the valve stem likewise passes.

The outer or discharge end of the steam pipe is exteriorly threaded and the corresponding end of the oil pipe is interiorly threaded as clearly shown in Fig. 1. By again referring to Figs. 1 and 2 it will be seen. that the difference between the diameters of the steam and oil pipes is suiiiciently great to provide a chamber which surrounds the oil pipe and is arranged concentrically thereof. The inlet openings for the steam and oil pipes are designated respectively by the numerals 19 and 17 and are located in the casings 7 and 8, which surround the inner ends of said pipe as before stated.

screw By reference now to Figs. l and 2 it will be observed that located directly below the points where the lower ends of the outlet passages open through the flange l2, there is formed in the latter a rectangular slot 23 yyhich communicates with the steam cham- In assembling the burner khead with the steam and oil pipes the threads on the inner end portion 13l and those on the lip l5 are brought into Yengagement with the threads on the discharge ends of the steam and oil pipes after which the burner is turned until the end edges of the-se pipesv bear on the inner face of the flange 12. When the parts are so positioned it is obvious that the oil during its passage to the head will be heated to an extent suiiicient to cause it to flow through the outlet passages in vaporized form, whereupon it will be taken up by the steam issuing through the slot 22, the deflection and divergence of said passages effecting a perfect admixture of the steam and vaporized oil. p

It is obvious that the steam issuing through the opening 23 will produce a siphoning effect on the oil vapor passing through the passages 1l and it will be further observed that the expansion of the steam and oil vapor will be checked in one direction by the outer or rectangular shaped end portion 14 of the head. This check will be suflicient to cause a thorough admixture of the oil vapor and steam since it can be readily seen that the oil vapor cannot rise beyond the lower surface of the outer end portion la until after the admixture has passed beyond the terminal of said outer end.

Another advantage gained by this construction is that the operation of cleaning the passages Vand valve seats may be easily accomplished by simply unscrewing the burner head, and it is well known that in burning crude oil considerable difficulty is experienced from the foreign matter in the oil clogging the oil passages.

It can be seen that with a device of this kind, the cleaning operation may be more readily effected than with other forms of these devices now in use.

vWhat we claim as new is l. In a hydro-carbon burner, a steam supply pipe having its opposite ends exteriorly screw threaded, an oil supply pipe located within and spaced from said steam supply pipe, said oil supply pipe being of greater length than the steam pipe and having one end in a plane with one end of the latter and interiorly screw threaded and its opposite or extending end exteriorly screw threaded, a casing having one end interiorly screw threaded to receive one of the threaded ends of the steam supply pipes, said casing being contracted at its intermediate por` tion and interiorly screw threaded to receive the lextending end of the oil supply pipe, a burner head having a portion threadable onto that end of the steam pipe remote from the casing and another portion threadable into the corresponding end of the oil supply pipe, said head being centrally provided with a valve seat and oil outlet openings extending obliquely to the long axis of the head and communicating with the valve seat, said burner head being further provided with a steam outlet opening spaced from and located below the oil outlet opening, and a needle valve having one end bearing in the free end of the casing and its .opposite end in the valve seat.

2. In a hydro-carbon burner, a steam supply pipe exteriorly screw threaded at one end, an oil supply pipe located within and spaced from said steam supply pipe and having one end in a plane with the threaded end of the steam supply pipe and interiorly screw threaded, a burner head having a cylindrical inner end portion exteriorly screw threaded and threadable into an oil supply pipe, and an outer rectangular shaped end portion extending considerably in advance of the adjacent end of the oil supply pipe, said burner head having a medially disposed annular flange terminating in an interiorly threaded lip to engage the threaded end of the steam supply pipe, said burner head being provided on its inner end with a centrally disposed valve seat and a steam outlet extending through the flange and further provided with a plurality of diverging oil passages spaced from the steam outlet and extending oblique to the long axis of the burner head and having their inner ends communicating with the valve seat and Jtheir outer ends extending through the inner ends of one face of the rectangular shaped portion of the head and at a point adjacent 'the ange, a casing secured to the ends of the steam and oil supply pipe remote from the burner, a needle valve having one end bearing` in the casing and its opposite end in the valve seat.

In testimony whereof we affix our signatures in presence of two witnesses.
